I don't understand why they would be getting very hot under no more load than that make sure the crimps are tight and the nuts are tight lose connection will cause heat. Now they will get warm under normal conditions after a long time running other wise maybe someone else can help you.

Same thing happened to me and melted the top of my cell before I caught it. Maybe too small wire, maybe too small bolt, maybe too much electrolyte, too many amps???? I am going to reduce the amount of NaOH I added and see what happens. I was running 11--12 v off a lawn mower battery and amps were measured at 6.45 cold and 9.5 hot. Was producuing great HHO at about 1 L per 1 1/2 Min. Still working on this. Please let me know your results.
